An apparatus to create corrugated cardboard on the site of a system for automatically forming packaging boxes for packaging an arrangement of one or more item(s) to be shipped, said corrugated cardboard having at least one corrugated layer between two flat layers, comprising at least two supply stations for supplying two different single-faced corrugated cardboards, each single-faced corrugated cardboard comprising a corrugated layer (having a closed side with an attached flat layer and an open side opposite to said closed side, a supply station for supplying a closing layer, a microprocessor communicatively coupled to obtain information on the arrangement to be shipped, the information relating to at least one of overall dimensions, weight, shape, shipping conditions, fragility, sensitivity to moisture, value, shipping destination, and the obtained information allowing selection, based on the obtained information, of at least one of said at least two different single-faced corrugated cardboards, and an attaching station that attaches the closing layer to the selected first single-faced cardboard to sandwich the corrugated layer between the flat layer and the closing layer.

The disclosure proposes a fibreboard made of lignocellulose-containing fibres, in particular wood fibres and a binding agent for providing a fibreboard which enables to combine a high stability, on the one hand, and a comparatively small weight, on the other hand, and which can nevertheless be manufactured with a minor financial effort.

The invention relates to a method for introducing a material web into a corrugating device having a corrugating roller for generating from the material web a corrugated web. The method comprises the step of attaching at least one double-sided adhesive tape piece which has a first adhesive face and a second adhesive face that is opposite the first adhesive face to the material web by means of the first adhesive face upstream of the corrugating device of the material web, and guiding the material web through the corrugating device in such a manner that the second adhesive face adheres to the rotating corrugating roller while entraining the material web for introducing the material web.

A corrugated cardboard plant comprises a corrugated cardboard web production assembly for producing a corrugated cardboard web; a register mark cutting device, disposed downstream of the corrugated cardboard web production assembly, for cutting the corrugated cardboard web into corrugated cardboard sheets; a register mark detection device, disposed upstream of the register mark cutting device, for detecting at least one register mark on the corrugated cardboard web; and a control assembly which is in signal connection with the register mark cutting device and with the register mark detection device, and depending on the at least one detected register mark actuates the register mark cutting device, while generating at least one register mark cut. The corrugated cardboard plant furthermore has a register mark cut position correction installation for the automatic correction of the position of the at least one register mark cut in relation to the at least one register mark in the case of an undesirable deviation of the position of the at least one register mark cut.

A corrugating machine for forming a flexible paper drinking straw by forming annular corrugations in a tube, including a plurality of corrugating elements and means for moving the tube against the corrugating elements. Each of the corrugating elements is spaced apart from each other in both a lateral direction and a forward direction. The corrugating machine includes an assembly spool and a drum mounted to a side of the assembly spool for rotation about a common axis. A mandrel is mounted to the drum for reciprocation into and out of the spool assembly, to carry the tube against the corrugating elements mounted in an arc defined about the common axis.

Systems for providing efficient manufacturing of sheet or box structures, corrugate sheets, or other products of varying size and structure often with pre-applied print (pre-print) are provided herein. The systems include various features and modules that enable automated control of the corrugator, including the knives, slitters, scorers and cut-to-mark detection system(s), are contemplated. Colored markings may be used to indicate an order change section between two order sections of a roll plan for the manufacturing process. The colored markings are detected as the corrugator runs and, once detected, a controller determines a next set of order instructionse.g., to match the upcoming order. Thus, an order change may occur, thereby enabling automated control of the corrugator based on the new order instructions. Computer readable markings may enable checking of the actual position in the roll plan to an intended position, enabling stopping or changing of the corrugator operation if needed.
